Re: [U-Boot] [PATCH V3] imx: i.mx6q: add the initial support for LogicPD i.MX6Q SOM

6 Apr 2017

...
Logic PD has an i.MX6Q system on module (SOM) with a development kit. The
SOM has a built-in microSD socket, DDR and NAND flash.  The development kit
has an SMSC Ethernet PHY, serial debug port and a variety of peripherals.
This have been verified to boot the i.MX6Q version over either SD
on the development kit or NAND built into the SOM.
Signed-off-by: Adam Ford aford173@gmail.com
Changes in V3:

Add OF_CONTROL and device tree
Switch to DM_I2C
Switch to DM_ETH
Switch to DM_MMC
Switch to DM_PMIC
Switch to DM_REGULATOR
Switch to DM_GPIO
Fix Ethernet reset to play nicely with DM_GPIO and DM_ETH
Remove more unnecessary code with DM enabled.

Changes in V2:

Alphabetize the modified Kconfig file
Clean up README file.
Elminate fdt_high and initrd_high and add bootm_size
Changed MTDPARTS_DEFAULT to increase the kernel size to 16MB
Cleaned up the mx6q_2x_MT41K512M16HA.cfg to include headers,
replace hard-coded addresses with human-readable ones, and
remove dead code
Updated mx6q_2x_MT41K512M16HA.cfg to use BOOT_OFFSET since SD
and NAND have the same offset
Removed 'ifdef' references that were always true.
Removed CPU references that didn't exist.
And made local variables static
Add reference to worked used to derrive this code

Usually the slave devices are specific to board, so it's better to
defined these in dts file instead of dtsi. And also I'm unable to
differnetiate SOC entries vs Board entries? Please check and if
possible move SOC entries in dtsi, this will be easy for longterm
mainataince.

+U-Boot for LogicPD i.MX6 Development Kit
+----------------------------------------



+This file contains information for the port of U-Boot to the Logic PD Development kit.



+Logic PD has an i.MX6 System On Module (SOM) and a correspondong development
+board.  SOM has a built-in microSD socket, DDR and NAND flash.  The development kit has
+an SMSC Ethernet PHY, serial debug port and a variety of peripherals.



+On the intial release, the SOM came with an i.MX6D and i.MX6Q.



+For more details about Logic PD i.MX6 Development kit, visit:
+https://www.logicpd.com/



+Building U-Boot for Logic PD Development Kit
+--------------------------------------------
+To build U-Boot for the Dual and Quad variants:


make imx6q_logic_defconfig
make u-boot.imx ARCH=arm CROSS_COMPILE=arm-linux-



+Flashing U-Boot into the SD card
+--------------------------------



+See README.imximage for details on booting from SD



+Flashing U-Boot into NAND
+-------------------------
+Once in Linux with MTD support for the NAND on /dev/mtd0, program U-Boot with the following:
+with:


kobs-ng init -v -x u-boot.imx

Since this board enabled-of the image should be u-boot-dtb.imx or
similar like dtb enabled image.
...



+Additional Support Documentation can be found at:
+https://support.logicpd.com/
